WBPhenotype:0000050
|
embryonic lethal
|
Animals die during embryonic development. In C. elegans, often assayed as refractile eggs that fail to hatch; when applied to large-scale RNAi screens in C. elegans, more than 10% of embryos die. |
|
WBPhenotype:0000059
|
larval arrest
|
The developmental program of the animals halts at any larval stage and thus fails to reach adulthood. In C.elegans, this occurs anytime during L1-L4 stage. |
|
WBPhenotype:0001037
|
sterile progeny
|
Any variation that compromises the reproductive ability of the progeny of an animal. |
|
WBPhenotype:0001155
|
pronuclei meet centrally early emb
|
The maternal and paternal pronuclei meet more centrally instead of meeting in the posterior end of the embryo. |
|
WBPhenotype:0001105
|
P0 spindle position abnormal
|
Altered P0 spindle placement causes either a symmetric first division, a division in which P1 is larger than AB, or a division in which the asymmetry is exaggerated such that AB is much larger than normal. |
|
WBPhenotype:0001082
|
large cytoplasmic granules early emb
|
Abnormally large granules are observed in the cytoplasm of P0. |
|
WBPhenotype:0001123
|
synchronous second division early emb
|
AB and P1 divide synchronously. |
|
WBPhenotype:0001109
|
P0 spindle rotation delayed early emb
|
P0 spindle rotates late in the inviable one- to four-cell embryo. |
|
WBPhenotype:0001134
|
Aba ABp division axis defective early emb
|
ABa or ABp divide in the wrong orientation. |
|
WBPhenotype:0001126
|
cell cell contacts abnormal in four cell embryo
|
Aba, ABp, EMS, or P1 contacts fewer of its sister cells than in control embryos. |
|
WBPhenotype:0001108
|
P0 spindle rotation failure early emb
|
P0 spindle fails to rotate and extends perpendicular to the long axis of the embryo. |
